Occasionally, I get foreign calls from our business partners, and I never pick them up because I don’t want them to interrupt my workflow. If they want to contact me, I expect them to email me.
I always wanted to automatically reject such international calls but never could. All the tutorials I could find suggested Android settings that my Android version didn’t support.
MacroDroid to the rescue!

That’s it! +36 is Hungary’s country number. Negating it blocks international calls.
MacroDroid is an extremely versatile tool that I highly recommend.
Thank you so much! I was looking for a similar solution but was unable to find a dedicated settings in Android.
This is such an easy fix. I added a custom notification that alerts me when a number is blocked, in case of an account activation that might require a foreign call to be accepted. That way I avoid forgetting about the macro and losing my mind. Cheers!
Glad to help, and great idea about the account activation notification! I may also add it.
